I think it is fair to argue against it, to a large extent. However, patents are techniques and methods to do something. This would almost be akin to a sport team getting exclusive use of a play because they registered their playbook first. Which, yes, sounds "wild."
I, sadly, don't know all of the details in this case. But with patents, remember that you don't even have to show that "Bob" even knew of the existence of "Bernie." They could have come to the same general techniques completely independently, but because they were not "first to file," they cannot use them.
(Obviously, if I am wrong on the above, please correct me.)
